This not only enhances performance but also enables you to make more efficient use of your hardware resources, potentially resulting in cost savings on infrastructure. Key metrics such as CPU usage, memory usage, and disk I/O offer insights into how efficiently your database server operates.

The GraphQL shim enabled client engineers to move quickly onto GraphQL, figure out client-side concerns like cache normalization, experiment with different GraphQL clients, and investigate client performance without being blocked by server-side migrations. So, we relied on higher-level metrics-based testing: AB Testing and Sticky Canaries.

One could argue this is a metric-driven decision. When they dug into the data, they found that the reason load times had increased was that they got a lot more traffic from Africa after doing the optimizations.

Setting up CI/CD : Although developers could come up with their own build and deployment pipelines, chances are that they are relying on some infrastructure provided by another team (eg an “infra” team). One could argue this is a metric-driven decision. Lots of case studies where changes in performance led to key metric improvement.

But there are parts of the world where mobile data is prohibitively expensive, and where there is little or no broadband infrastructure. These countries generally have a combination of poor technical infrastructure and low adoption, meaning data is both costly to deliver and doesn’t have the economy of scale to drive costs down.

The scale of the effect can be deeply situational or hard to suss out without solid metrics.
